Diet: Stegosaurus is said to have eaten mosses, ferns, horsetails, cycads, conifers, and fruit

Anatomy: Stegosaurus has teeth and jaws that differ from that of other ornithischian dinosaurs. This is due to the diet of the dinosaur. What stegosaurus is known for is its back plates and its spiked tail. The purpose of the plates is still a debated matter. Some say that the plates had some role in protection, but it is debated that they aren't due to the fact that the plates were kinda frail and thin. The plates have been found to have the ability to change color via blood flow, whether it be for attracting mates or threatening predators. Last interesting part of the stegosaurus is its second brain. This is said to be a glycogen body, which helps in the nervous system. This is found throughout many dinosaurs.

Behavior: Stegosaurus is a social animal, living in very small herds. It spent its days roaming and grazing.

Reproduction: Not much is known about its reproduction or how many eggs it laid. Juveniles would measure up to 1.5m long.

Relationship with other animals: Stegosaurus lived with a well known predator, allosaurus. Based on the findings of allosaurus, it was not lucky in hunting this animal, as many have been found with marks of an encounter with stegosaurus.

Diet: The cave bear mainly ate plants, but would switch to animals if needed

Anatomy: Cave bears were one of the larger bears. It had a different set of teeth than other bears, as shown by the loss of premolars.

Behavior: Like most bears it was solitary

Reproduction: No data

Relationship with other animals: Humans and cave bears did not meet much, but humans of that day may have fought the bears for caves. It is also shown that they worshiped the bears as a god. Cave lions were predators of the cave bear. Only slightly bigger than a lion, but bulkier. The cat was powerful enough to take down the bear.

Anatomy: Like dogs and cats, goldfish have variations. Some, like the celestial eye, have upwards pointing eyes, and the lionchu which has a large head. Goldfish also lack a stomach.

Behavior: Goldfish normally live well in groups, and usually swim and eat

Reproduction: Th goldfish can reach sexual maturity due to the water it lives in nutrition. They will lay eggs on aquatic vegetation. The eggs hatch in 49-72 hours. Within a week the fry will grow into its adult form.

Relationship with other animals: The goldfish is used by humans usually for decorations. Goldfish are used to eat mosquito larvae, though it does benefit people, it damages the ecosystem. They little predators they have would be the house cat, though it takes a bad pet owner to let the fish get eaten by it.

Behavior: These lizards are durnial. They are full of energy and they are solitary

Reproduction: This is why this lizard is interesting. There are no males in this species. These animals reproduce by parthenogenesis. But there is a reason we call them the lesbian lizard. These lesbians can't lay eggs till they mate. Meaning only a female mounting another can help he ovulate. She lays up to 3-5 eggs

Relationship with other animals: This animal is quick to escape predators, usually birds of prey.

I have no jokes, as I have no friends who happen to be lesbians.
